Abstract:
Accordingly, certain embodiments of the invention provide a conjugate of formula (I): P-(X-D)n, wherein P is a peptide that binds to a glucose regulated protein 78 (GRP78); X is a direct bond or a linking group; D is a detectable agent; and n is 1 to 4. Certain embodiments of the invention provide a pharmaceutical composition comprising a conjugate of formula (I) and a pharmaceutically acceptable excipient. Certain embodiments of the invention provide a method for treating or preventing cancer in an animal (e.g., a human) comprising administering a therapeutically effective amount of a conjugate of formula (I) (e.g., a conjugate comprising a therapeutic radionuclide) to the animal.
Abstract:
This disclosure provides radiolabeled compounds that bind to guanylyl cyclase C (GCC) and which can bind cancer cells that express GCC. Exemplary compounds comprise a chelating moiety capable of binding a radioactive atom, a peptide capable of binding GCC, and a linker moiety connecting the two. This disclosure also provides methods of detecting and treating cancer using the compounds described herein.
